London Mayor Sadiq Khan gave the greenlight to activists to fly a giant balloon depicting an orange baby Trump throwing a tantrum during the U.S. president’s visit.

“The Mayor supports the right to peaceful protest and understands that this can take many different forms.” a spokesperson for the mayor told Huffington Post. “His city operations team have met with the organizers and have given them permission to use Parliament Square Garden as a grounding point for the blimp.”

A crowdfunding campaign to fly the 6-metre blimp raised over £16,000.

“When Trump visits the UK on Friday the 13th of July this year, we want to make sure he knows that all of Britain is looking … and laughing at him,” the campaign page said.

“We didn’t get off to the best start with the mayor’s office over this, who originally told us that they didn’t recognize Trump Baby as legitimate protest,” activist Leo Murray told Sky News. “But following a huge groundswell of public support for our plan, it looks like City Hall has rediscovered its sense of humour. Trump Baby will fly!”

A petition to the Mayor Khan’s office to let the balloon fly collected over 10,000 signatures.

British actor Luke Evans tweeted his pride at being a London native upon reading the news.
